Syntax

Remarks

Using this class to display port handles will result in exceptions if the
underlying port instances are removed from the graph while the handles are
displayed. This can happen, for example, through
Undo or if ports are removed programmatically with
Remove(IPort). In that case,
you need to query the handles again before interacting with the graph, for
example by temporarily unselecting and reselecting the port-owning nodes.
